Abstract: A mixed reality-based remote operation guidance system and method. The system comprises an AR client, a VR client, and a central server. The AR client transmits a collected on-site video to the VR client by means of a network, for rendering a video stream to an interactive virtual plane in a three-dimensional space. The VR client transmits, to the central server by means of the network, content annotated on the virtual plane by an expert, for fusion of virtual annotation and an on-site three-dimensional reconstruction model. The central server transmits fused data to the AR client by means of the network, for implementing fusion display with a physical space. The method can eliminate information blind spots in remote operation guidance, and solve the problem that complex operation guidance intentions cannot be accurately and visually expressed due to a single interaction mode and low interaction dimension in the remote operation guidance.

Abstract: The present application provides an antenna and a mobile terminal. The antenna comprises a feeding unit and a radiating unit. The feeding unit is connected, by means of a power splitter, to a first radiating unit and a second radiating unit that are electrically isolated. The power divider is used for adjusting the difference between the maximum point of the pattern of the first radiating unit and the maximum point of the pattern of the second radiating unit to be within a set range. The first radiating unit is connected to a phase shifter. The phase shifter is used for adjusting the direction of the pattern of the first radiating unit and making the maximum point of the pattern of the first radiating unit and the minimum point of the pattern of the second radiating unit at least partially overlap and the minimum point of the pattern of the first radiating unit and the maximum point of the pattern of the second radiating unit at least partially overlap. During use, by adjusting the power splitter and the phase shifter, the phase difference and amplitude difference between multiple radiating units are changed, so that the directivity of a single radiating unit is reduced, and the depressed point of the radiation pattern becomes smaller, thereby improving the antenna communication effect.
